C desperately wants to play with the twins at all times, but especially when Hubs rough houses with them. So he invented "m'attack chicken!"
It's played like this: Hubs holds C in front of him with his toes grazing the floor, like he's going to help him walk. Then they cry, "Balk! Balk! Balk!" And chase the screaming, balking twins all over the house.
When they "catch" the twins, C "attacks" them by climbing on top of them. C laughs like crazy, Hubs balks like a mad chicken, the twins scream and holler with glee.
